Mouse Button Test

Click every button and roll the wheel to confirm each one registers — including the side buttons most tests miss.

Click each button and scroll inside the box.

Right-click, middle-click and side buttons won't open menus or go back while you're inside this box.

How to Test Your Mouse Buttons

  1. Move the pointer into the test area.
  2. Press each button once: left, right, middle (press the wheel down), then the two side buttons.
  3. Roll the wheel up and down a few notches.
  4. Each part of the mouse diagram fills in once it has registered. When Buttons tested shows 5 / 5, every button works.

The event log lists every press, release and scroll step with a timestamp, so you can see exactly what the computer receives. Hold time shows how long the last button was held down — useful for checking that a button doesn’t release on its own during a drag.

What Each Mouse Button Is

Button Browser name Usual action
Left Button 0 (primary) Select, click, drag
Middle Button 1 (auxiliary) Open link in new tab, autoscroll
Right Button 2 (secondary) Context menu
Back Button 3 Previous page
Forward Button 4 Next page

Gaming mice with more than five buttons usually send the extra ones as keyboard shortcuts set in their software, so they appear in a keyboard test rather than here.

Common Mouse Button Problems

A Button Doesn’t Register at All

Try another USB port and, for wireless mice, a fresh battery. If the button still does nothing, check the mouse software: buttons can be disabled or remapped. If that’s not it, the microswitch under the button has probably failed.

A Button Registers Twice

One press showing as two clicks is called switch chatter or “double-clicking”. It’s the most common fault in older mice and is caused by worn or oxidised switch contacts. Use the double-click test to measure it.

A Held Button Drops Out

If Hold time is shorter than you actually held the button, or the log shows an “up” in the middle of a press, the switch is losing contact. This breaks drag-and-drop and holding fire in games — the same worn-switch problem as chatter.

The Scroll Wheel Skips or Reverses

Scroll wheels use a small rotary encoder. Dust or wear makes it miss steps or report the wrong direction. Watch the up/down counts while rolling slowly in one direction: any count in the wrong column means the encoder is misreading.

When to Repair or Replace

Switch and encoder faults are mechanical, so drivers and settings rarely fix them. Many gaming mice are covered by a 2-year warranty, and some use socketed switches you can swap without soldering. For a cheap office mouse, replacement is usually the practical fix.

Frequently Asked Questions

Why Don't My Side Buttons Show Up?

Most mice send side buttons as "Back" (button 4) and "Forward" (button 5). If neither lights up, the mouse software may have remapped them to a keyboard key or macro, or the buttons are disabled in an on-board profile. Reset the profile or check the vendor software.

Why Does My Scroll Wheel Jump in the Wrong Direction?

A wheel that sometimes scrolls the wrong way usually has a dirty or worn rotary encoder. Short bursts of compressed air around the wheel often fix it; if not, the encoder needs replacing.

Can This Test Detect a Double-Clicking Mouse?

This test shows every press, so you may spot one, but the dedicated double-click test is better — it times every click and flags ones that arrive impossibly fast.

Does the Test Work with Wireless and Bluetooth Mice?

Yes. Any mouse your computer recognises works, wired, 2.4 GHz wireless or Bluetooth. If buttons register late or not at all only when wireless, check the battery and move the receiver closer.

Why Does Right-Click Not Open a Menu Here?

The test blocks the right-click menu, middle-click autoscroll and back/forward navigation inside the test area so every press can be recorded without leaving the page.
